Nonlinear control affine systems with maximum relative degree and a class of nonlinear differential equations can be transformed into a state representation known as the normal form. Based on the normal form an observer is designed using neural netwo... Read More about Neural observer by coordinate transformation.

An investigation of the effect of feedback on TLM nodes representing heat transfer (2005)
Journal Article
Koay, A. L., Pulko, S. H., & Wilkinson, A. J. (2005). An investigation of the effect of feedback on TLM nodes representing heat transfer. International journal of numerical modelling, 18(6), 399-411. https://doi.org/10.1002/jnm.586

TLM is a very successful technique for modelling thermal transients in heat transfer systems. However, useful though transient modelling is, there are many systems in which the desired thermal behaviour can only be obtained by direct, real-time inter...

Amplitude and frequency estimator of a sinusoid (2005)
Journal Article
Hou, M. (2005). Amplitude and frequency estimator of a sinusoid. IEEE transactions on automatic control, 50(6), 855-858. https://doi.org/10.1109/TAC.2005.849244

A dynamic estimator with global convergence property is proposed to simultaneously reconstruct the unknown values of the amplitude, frequency, and offset of a sinusoidal signal which is measured. Several versions of the estimator along with illustrat... Read More about Amplitude and frequency estimator of a sinusoid.

Tuning of electronic coupling between self-assembled quantum dots (2005)
Journal Article
Rybchenko, S., Itskevich, I., Skolnick, M. S., Cahill, J., Tartakovskii, A. I., Hill, G., & Hopkinson, M. (2005). Tuning of electronic coupling between self-assembled quantum dots. Applied physics letters, 87(3), 033104. https://doi.org/10.1063/1.1995953

Semiconductor self-assembled quantum dots (SAQDs) normally have zero-dimensional properties, but become coupled and acquire higher-dimensional character if the distance between the dots is small. Using photoluminescence spectroscopy under high hydros... Read More about Tuning of electronic coupling between self-assembled quantum dots.

Observing a three-tank system (2005)
Journal Article

Observability analysis and observer synthesis are studied for a three-tank water process. Observability of the process is considered under various assumptions on measurements. The observer design takes into account singularity of nonlinear observers.... Read More about Observing a three-tank system.

Controllability and elimination of impulsive modes in descriptor systems (2004)
Journal Article
Hou, M. (2004). Controllability and elimination of impulsive modes in descriptor systems. IEEE transactions on automatic control, 49(10), 1723-1729. https://doi.org/10.1109/TAC.2004.835392

As a refined notion, impulsive-mode controllability is suggested for the general class of linear continuous descriptor systems. This notion reveals rich properties of the general descriptor systems in terms of admissibility of initial conditions, adm...

High pressure provides an efficient way of controlling the electronic properties of semiconductor nanostructures. We use pressure to tune electronic coupling in stacks of self-assembled quantum dots (SAQDs). The coupling occurs as soon as the distanc...

Temporary balloon catheter occlusion for control of haemorrhage following penetrating axillary artery injury (2004)
Journal Article
Mehta, T., Venkata Subramaniam, A., Chetter, I., Nicholson, A., & Wilkinson, A. (2004). Temporary balloon catheter occlusion for control of haemorrhage following penetrating axillary artery injury. European Journal of Vascular and Endovascular Surgery Extra, 8(2), 29-30. https://doi.org/10.1016/j.ejvsextra.2004.05.014

Penetrating injuries of the axillary artery are uncommon. Their repair can be difficult in the presence of torrential haemorrhage, which obscures the surgical field. We describe the use of interventional radiology for temporary control of bleeding to...

There is a growing market for food producers to supply their goods direct to customers, which has largely been brought about by the growing popularity of web-based ordering. However, the geographical distance between supplier and consumer can be larg... Read More about Wrapping strategies for temperature control of chilled foodstuffs during transport.

The value of abdominal examination in the diagnosis of abdominal aortic aneurysm (2004)

Background. There is considerable variability in the reported value of clinical examination in the diagnosis of abdominal aortic aneurysms (AAA). This study aims to assess accuracy of abdominal examination by a doctor, a nurse and the patient in the...
